I have a layout that has 2 columns.

-----------------------------------
| 111111 | 222222222222222222 |
| 111111 | 222222222222222222 |
| 111111 | 222222222222222222 |
| 111111 | 222222222222222222 |
-----------------------------------

Section 2 on some sections of the site goes on for several pages, section 1 has only a navigation menu in it. Is there a way to make the size of 1 the same as 2. I would like to make the height of 1 the same size as 2 dynamically. How can this be done?
